CARBURETER.

To all whom it may concern:

Be it known that I, JOHN ANDERSON PAT- nnsoN, a subject ot' the King of `Grreat Britain, residing at W'ellington, in the Dominion of New Zealand, have invented .a new and useful Carbureter; and I do hereby declare the following toA be a full, clear, and exact description of the same.

This invention has been designed specially in order to provide for the satisfactory production of gas from hydro-carbon oils for use for power purposes such as the driving of motor car, launch, and other gas, and oil engines.

In order to effect this purpose, the invention consists in the provision' of means whereby the exhaust from the engine will be employed to warm the' carbureter, the air admitted to such carbureter for the production of the gas, and the air utilized for the attenuation of the rich gas in order to reduce it to the proper explosive mixture.

In carrying out the invention, the exhaust is caused to passthrough a chamber in which the carbureter is placed and through which pipes for conveying the air to the earbureterand the air for admixture with the. gas, are arranged. In the chamber 'also may be placed the mixer in which the and attenuating air are mixed together, so that the whole Voperation of producing and atten'uating the gas for supplying the engine may be carried out in'. a chamber warmed by vthe heat from the exhaust passing through it.

In describing the invention, reference will be made to the accompanying sheets 4of drawings in which twol alternative forms of apparatus are shown. and in wli icli,-

Figure 1 is a sectional elevation of one form of :the appliances employed. taken 'on the lined-1 ofFigs. 2 and 3. Fig. 2 is a similar section taken on the line Q--Q of Fig. 3. Fig. 3 is a sectional plan taken on the line-S ot Fig. 1. Fig. 4 is a sectional elevation of the second or alternative manner of carrying out the invention. Figs. 5, 6 and 7 are sectional plans taken on the lines 5-5, 6 6 and il-7 respectively oit Fig. 4. l y

Referring first to Figs. l to- 3,-a is a. chamber of approved size and shape in cross section, into the top end of which the exhaust is led through the opening b and from the bottom of which' it passes through the opening c. Thisv chamber may be of any Specification of Letters Patent.

approved shape. In vthe drawings it is Patented Dec.` 1.2, 1911 Application filed May 19, 1909. Serial No. 497,075.

shown ascylindricah ithin the chamber is placed the carburetor d which may be of anti7 approved type, but .preferably of the dry or surface type in which the air to be carbureted is 'caused to pass-down through an absorbent material c kept saturated with t-he eil employed. This carbureter is so arranged within the exhaust. chamber a. as to leave a space all around it and it is provided with a cone shaped top inc-losing an air chamber g, and the ape-x of which is 'placed immediately below the exhaust inlet b. This cone surface will thereby serve to .break up the enteringexhaust gases, and guide them equally around the whole external surface of the carbureter. The air chamber g is in communication with the carbureter proper through' apertures h the openings of which are regulated and governed -by the revolving plate j having corresponding apertures -adapted to coincide with or to be out oit from the apertures 7L. This plate is operated by tooth and pinion gearing 7i: (F ig. 2) extending to without the exhaust chamber a.. The' oil forsat-urating the absorbent e is delivered on to it through the perforating ring` a' connected with a supply pipe g/ as shown in full lines in Fig. l, and in dotted lines in Fig. 3.

The air for admission to the ai r chan'lber g is led up through the pipes Z Z, Figs. 2 and 3, which pass from the bottom of the exhaust chamber n, up through the space between such chamber and the carbureter. and into the air chamber g. The air for admixture with the gas produced in the carbureter is lcd through the pipes m, m, extending from the bottomof the chamber a. up through the space `around the carbureter. These pipes, at their upper ends, are then respectively connected to similarly situated downwardly extending-pipes n, n, which, at their lower ends, turn inward and connect with a single pipe o leading upward to the mixer p. Thus, the air will pass up through the pipes m. and then down the pipes n. and up again through the pipe 0 to the mixer 7).' This course of, the attenuating 'air is clearly shown in the drawings. The

pliance,.is also placed within the space surrounding the carbureter. Freni the mixer, the gas is led away to the engine through the outlet t. The passage of the gas from" the npipe s will be controlled by means vof a disk valve 'u Fig. 2, or the like, operated from Without the chamber. The amount ci attenuating air assing to the mixer will also be eontrolle by means of a stop cock .K of' valve w, Eig. 2, governing the passage through the pipe o.

The air pipes Z, m, and n, are arranged at regular intervals apart within the space surrounding the carbureter, and each one at its lower end is firmly attached to the bottom of the exhaust chamber a, While itsupper end is firmly attached to the carbureter. Tlese pipes thus serve as stays to hold the carbureter rmly 'in its proper position within the exhaust chamber. Any desired number of pipes thus arranged, may be employed according to the various requirements of the case.

It will be seen that as the exhaust gases pass through the chamber a, they will serve to warm the carbureter, the air pipes arranged in their passage, and the mixer p partments in its top end for receiving re-- y spectively the air to be carbureted, the air for admixture with the generated rich gas a'nd the gas itself. These compartments 'are numbered respectively 8, 9, and l0. The pipes Z for conveying the air to be carbureted, pass ,up through the bottom of the exhaust chamber a and into the compartment 8 and from thence the air passes through the inlet valve y' into the cabureting chamber e. The air for mixing with the gas passes up through the bottom of the chamer a, through the pipes m, and into the compartment 9, and-may then be allowed to pass in governed quantities, lthrough the inlet valve 11, into the compartment l0 above. The gas collected inthe bottom of the carbureter will passup through the pipes A12 into the compartment 10V and from thence will be drawn away through the outlet t, withthe attenuating air, to a mixer outside the appliance, or dlrect to the engine, if so required. It will be'noted that' each series f of pipes Z, mand 12 pass withi'n thesspace between thecarbureter d. and the exhaust chamber a sp'that the air and the gas passing witnesses.

ing up through such pipes will be heated by the exhaust gases passing through the space. The valves j and 11 being under control, the amount of air Aadmitted to the carbureting chamber, and to the compartment 10 for attenuating the gas, maybe regulated to any 4desired amount. It lwill be readily understood that only a portion of the exhaust may be caused to pass' -ated mixture of vapor and air, both said air conducting means being adapted to be heated by the gases in said exhaust chamber.

A 2.4In a carbureter, in combination, a chamber arranged Within the passage of the exhaust from a gas'or oil engine, a carbureter placed within such chamber, an air chamber above the carbureter, openings between such air chamber and the carbu-4 reter, air pipes passing through the exhaust chamber and entering the air chamber, a mixing compartment within the exhaust chamber, connections between such.

compartment and the carbureter, and air pipes passing through the exhaust chamber to the mixing compartment, substantially as specified.l

3. In a carbureter in combination, a chamber arranged within the passage of theexhaust from a gas or oil engine,a carbureter placed Within such chamber, and

arranged to leave a space all around it, a.

mixing compartment placed within the chamber and connected with the carbureter, pipes extending upward from the bottom of' the chamber, and through the space surrounding the earbureter fastened at their lower ends to the chamber, and at their up per ends to the carbureter, such pipes serving to convey air to the carbureter and to the mixing compartment, substantially as specified'.

In testimony whereof, I have signed this specification in the presence of two subscrib- JOHN ANDERSON PATEBSON.
